摘要
随着城市地铁隧道的发展,盾构法隧道施工越来越多,长距离小半径曲线盾构法地铁隧道施工关键技术研究,直接影响项目的安全、质量、进度及经济效益。在修建郑州地铁1号线时,我标段的郑州大学站至碧沙岗站盾构区间平面线形为"S"曲线,平面最小曲线半径为320m,曲线长度达897m,各项施工技术参数均受控。
Along with the development of urban metro tunnel, shield tunnel construction method is increasing, shield tunnel construction method with long and small radius curve is the key techniques, and is directly influences the safety, quality, progress and economic benefits of project. When building Zhengzhou metro No.1 line, shield zone horizontal alignment of our contract section from Zhengzhou university state to Bishagang state is ＂S＂ curve, the minimum planar curve radius is 320m, the length is 897m, and the construction technology parameters are controlled.
